Abstract: A user equipment (UE) is configured to prioritize a plurality of Public Land Mobile Networks (PLMNs) from an aggregate roaming priority public land mobile network (RPPLMN) list containing the plurality of PLMNs into a plurality of prioritized PLMNs and connect to a selected PLMN from the plurality of prioritized PLMNs based on a priority of the selected PLMN. The UE is further configured to determine if an application processor (AP) assisted location service is available, wherein the AP-assisted service is configured to identify a plurality of deployed PLMNs and a plurality of frequencies used by the plurality of deployed PLMNs at a current geographical location of the UE and when the AP) assisted location service is available, determining if a registered PLMN (RPLMN) is valid in a current mobile country code (MCC).

Abstract: Methods and apparatuses are disclosed for requesting and providing service of a network slice deemed essential by a user equipment (UE). The UE transmits a request message to the network indicating that essential services are requested, and identifying the essential network slice. Based on the information in the request message, the serving network communicates with one or more network nodes to determine whether the requested services can be provided. This information is packaged in a response message and transmitted to the UE. If the current network is capable of servicing the requested network slice, then the UE remains with the current network. If not, then the UE initiates a search for an alternative network (PLMN or SNPN) capable of supporting the requested services. A successful search causes the UE to register with the newly-found network, whereas an unsuccessful search causes the UE to re-register with the current network.

Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.

Abstract: The exemplary embodiments describe devices, systems and methods for implementing various exemplary techniques related to fifth generation (5G) new radio (NR) cell search. A user equipment (UE) selects a frequency band to scan during a cell search procedure and identifies a frequency within the frequency band that is associated with a synchronization signal block (SSB) based on an indication of the frequency stored locally at the UE prior to the cell search procedure. The UE then scans the frequency for the SSB and determines that the SSB has been broadcast by a cell over the frequency.
